As shown in the drawings, the throat formingrdeifice, which ie `designated; genorally by the letter o, is carried in iXed position by the head b, Wh'iehis movable yeitically With respect tothe traine c oth-the I The caps* et ere adapted to be laterally into operative `position througli nchnnel afin the heed The head is prrnfided;with` niplnnger fwhieh isifadpted i to ybear upon the enpsfduringthe sealing operation and to belforcecl `npvvardly against `the presenre otspring g to permit the throat iorining .device to pnlssyover the bottle head and cap. ils"` this inventionie limitedto the throat forming Vdevice no fiirther description Willbe given o' the rest of the see-ling maehine,"fthie type of Inzichine `being Welllinen/nin the ern i i i `Referring to Figs; tend 5, "the throat forming device:comprisesai plurality of "segniente l, preferably mede of hard nietel; torminga! ringrwhich is hereindeeignated als thethroat forming ring; The rear "feces of these segments are formed adjacent the top `and bottom thereof with inclined Snrineen',` the upper el theeeeur'li'acee being1r 1in-f clined clo-nniwirdly and jin\va1clly,nS1 shown et `Q, `and the lower beinginclined upwardly and inwr rdly, es shownnt 3; y y l The sn' Faces; 2 end 3 `are engaged byeorreepondngly inclined surfaces ot an upper ring `4 "zt-nd "e lower# ring irespectiifely.`

These ringesnrroiind the Segmente lend are nioynble towards, each other to permitthe expaneion `of the throat forming ring" from its normal position,` the` moyelnentot the ringe "and 5 towards each other being re sisted byepringsi 6 cio-acting with opposite 'feces of seid rings e and 5. Thelatter rings are formed of herdl inziterial,` preferably metal. y A" cylindrical casing 7, preferably of inetal,` Surrounds the `rings"v l and und Springe (3 and Serves to retain the veri-ons parts `in position. The rings el.- and are slidable in this casing longitudinally olf the axis of the device.

The segments i are desirably beveled olf or tapered at the ends ot the inner sur-tace of the throat, as shown at 8, to facilitate the passage of the throat over the bottle head and cap. In use as the throat forming); deviceipasses over the bottle head and cap, as shown in Fig. 2, the slrirtof the cap l is first engaged by vthe surface y8 and as the said device `passes down further, the bottle with the cap thereon passes into the throat and the skirt oiithecap t'orced inwardly. lllh'en Lthe bottle head and cap have passed .:ompletely into the throat` as shown in Fig.

3, the skirt of the cap has been Ytorced down into sealing position. It will. be seen that even when thebottle head and cap are ol' abnormally large size, the segments l are `moved outwardlyv automatically during the capping operation against a predetermined "pressure, the rings4 and 5 beingtorced ton wards each other by the wedging action ot the coacting surfaces of segments l and rings 4 and 5 against the pressure ot spring 6, It vwill also be seen that when the bottle head is otlcenter oreccentric, the segments on one side are movable outwardly independentlyV of the segments on the opposite side .of the device. ldlhile the' segments yield as required, a predetermined pressure is maintained .upon the skirts ofv the bottle caps through the resistance to the yielding ofthe segments. As soon as the capping operation is complete, the spring 6 andthe rings4 and 5 force the segments l'baelr to their original innermost position by the separationof the rings 4 and 5 and the wedge action of thesaid rings on the segments l.

The term of the invention shown in Figs. Gand 7 is provided with segments l and rings 4 and 5 formed and coacting with each other the sam'e as the corresponding parts in Figs-4 and 5. Instead, however, of employing` springs to 'resist the movement et the rings 4 and 5 towards each other.I there is provided a ring' l0 of plastic resilient materiahsuch as rubber... This ring engages `the'opposite `faces of the rings 4 and 5 and the peripheral central portion of the throat forming ring. Casing l1 surrounds the rings 4, 5 and 10. `Tliis casing is similar to casing 7 of'Figs. 4 and 5 except that it is provided with openings or perforations 12 into which the material of the ring l0 is adapted, to be forced by a movement of the rings 4 and 5 towards each other. The amount of pressure exerted by the ring' l0 on the rings 4 and 5 can be varied by variations in ,size'and number ofthe openings or perforations l2. y

While I have shown two forms of my invention, it is to be understood that many changes may be made in the forms ol' invention shown without departing l'rom the spirit ot the invention.

Having thus described my invention, what I desire to secure by Letters Patent oi the United States is:
